Abstract:
Management strategies were compared, including thinning and the production of fuelwood versus larger size-class volume, to develop a management plan for the mesquite woodland of the southern Arizona study site. Pre-commercial thinning of mesquite stands is not economic and the production and separate marketing of the larger size class at current stumpage rates gives only marginally higher returns than fuelwood alone, $9.57/ha/yr compared to $9.13/ha/yr. Equations were developed for prediction of fuelwood volume and for estimating volume in stem pieces 20 cm or greater in diameter. Estimated growth rates were 0.43 m3/ha/yr for the upland areas and 0.84 m3/ha/yr for the riparian areas. The culmination of mean annual increment suggests a rotation age of 40 years.
